DETAILED DESCRIPTION

[0066] The following is a detailed description of embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0067] References to "one embodiment" or "an example" or "an example" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment disclosed in the present utility model. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0068] In the existing water-filled bowl structure, the inner pot is mostly fixed by clamping the edge of the inner pot in the middle through the middle ring and the bowl body, the middle ring and the bowl body are connected by threads, and the two sides are against the upper and lower surfaces of the inner pot edge to achieve the sealing and fixation of the inner pot. Therefore, after removing the middle ring, the user still needs to pick out the inner pot from the bowl body, which is not only time-consuming and laborious, but also easy to contact the food in the inner pot and get burned, which is inconvenient to operate and has poor safety.

[0069] In order to solve the above technical problems, the utility model provides a heat preservation bowl, such as Figures 1 to 13As shown, the heat preservation bowl includes a hand-held structure 100, an inner bowl 200 (i.e., the inner bowl) and a base 300. The hand-held structure 100 includes a fixing ring 110 and a hand-held handle 120 fixedly connected to the fixing ring 110. The base 300 has a heat preservation cavity, and the top of the base 300 is detachably fixedly connected to the fixing ring 110.

[0070] The inner bowl 200 is at least partially accommodated in the heat preservation cavity, and, as Figures 13 to 18 As shown, one of the outer wall of the inner bowl 200 and the inner wall of the fixed ring 110 has a plurality of first connecting tenons 410 distributed circumferentially (the figure shows the situation of being arranged on the outer wall of the inner bowl 200), and the other of the outer wall of the inner bowl 200 and the inner wall of the fixed ring 110 has a plurality of first connecting grooves 420 distributed circumferentially (the figure shows the situation of being arranged on the inner wall of the fixed ring 110), and the plurality of first connecting tenons 410 can be screwed into the plurality of first connecting grooves 420 one by one as the inner bowl 200 and the fixed ring 110 rotate coaxially relative to each other, so as to detachably fix the inner bowl 200 and the fixed ring 110.

[0071] In the heat preservation bowl provided by the present invention, the inner bowl 200 and the base 300 are directly connected to the fixing ring 110 of the handheld structure 100, and the base 300 can be removed from the fixing ring 110, so that the user only needs to disassemble the handheld structure 100 and the base 300, and then hold the handheld handle 120 of the handheld structure 100 to take out the inner bowl 200 connected to the fixing ring 110 from the base 300 (such as Figures 8 to 11 As shown in the figure, the inner bowl 200 can be conveniently taken out when needed to cool the food inside by using the surrounding air, which improves the convenience of taking food. When taking out the inner bowl 200 from the base 300, the user can move the position of the inner bowl 200 by the hand-held structure 100, without having to directly touch the inner bowl 200, thus avoiding the risk of the user being scalded by the inner bowl 200 and ensuring the safety of the use of the heat preservation bowl;

[0072] In addition, a first connection tenon 410 and a first connection groove 420 are formed on the inner bowl 200 and the fixing ring 110 of the handheld structure 100, respectively. The first connection tenon 410 can be engaged with the first connection groove 420 in a one-to-one correspondence, so that the inner bowl 200 is detachably fixed to the fixing ring 110 of the handheld structure 100. When the inner bowl 200 needs to be taken out of the fixing ring 110, the user only needs to briefly touch the outer surface of the inner bowl 200 to make the inner bowl 200 and the fixing ring 110 rotate relative to each other, and make the first connection tenon 410 and the first connection groove 420 staggered. The inner bowl 200 and the handheld structure 100 can be separated by a simple action, which improves the convenience of users in disassembling and assembling the heat preservation bowl, and further reduces the risk of users being scalded by the inner bowl 200, thereby ensuring safety in use.

[0073] In addition, the connection structure between the inner bowl 200 and the fixing ring 110 is simple, which reduces gaps and corner structures that may hide dirt, thereby improving the convenience of cleaning the inner bowl 200 and the handheld structure 100, and helping to keep the surface of the insulation bowl clean.
